Description

Technical Field

[0001] This utility model relates to the field of drinking water appliance technology, and in particular to a quick-opening, non-plastic-contact-water sealing cup lid and cup. Background Technology

[0002] In drinking vessels, water cups are used to hold water or other liquids. A cup typically has a lid that fits snugly against the body to seal it. Currently, the lid and body are usually sealed with a threaded ring, which does provide a tight seal, but requires several turns to tighten and loosen, making it cumbersome. Furthermore, misalignment between the threads on the lid and the body can lead to leaks. Additionally, the lid contains various plastic parts that come into contact with the water; if these parts are substandard, prolonged contact with the water can significantly impact health. Therefore, based on the shortcomings of existing technology, improvements to the lid and body are urgently needed. Utility Model Content

[0017] Preferably, there is also a cup shell for protecting the cup body.

[0018] (III) The technical effects to be achieved

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] Firstly, the inner cover of this utility model is equipped with a locking mechanism capable of radial contraction and expansion. A self-priming water-sealing device is located in the middle of the lower end face of the inner cover. The inner cover also has a locking mechanism for fixing the position of the outer cover after it moves relative to the inner cover. Furthermore, the inner cover has a switch device for unlocking the locking mechanism, with the upper surface of the switch device on the outer cover. This design allows for easy opening and closing while providing a more effective water-sealing effect when the cover is tightened. Moreover, there is no plastic contact throughout the process, further enhancing the healthiness of the drinking water.

[0021] Secondly, the self-priming water sealing device of this utility model includes a fixed base integrally formed with the end face of the inner cover, an mounting base is provided on the fixed base, a return spring is provided between the fixed base and the mounting base, and a self-priming water sealing component is provided on the mounting base. This arrangement is reasonable and the structure of the self-priming water sealing device is also relatively reasonable, which is convenient for manufacturing. At the same time, the self-priming water sealing component is conducive to buffering and sealing under the action of the return spring, which is more conducive to meeting the user's needs.

[0022] Thirdly, this utility model includes a cup body made of a self-absorbing water-sealing material. The cup mouth of the cup body is provided with a quick-opening, non-plastic-contact water-sealing lid as described above. For this application to a water cup, this method eliminates the need for rotational closing and opening of the existing threaded structure, creating a new method where the quick-opening, non-plastic-contact water-sealing lid can be pressed to seal tightly onto the cup mouth. This avoids the leakage problem caused by multiple rotations and incomplete sealing of the threaded method. Then, simply pressing the switch device in the quick-opening, non-plastic-contact water-sealing lid is all that is needed to open it. The operation is quicker, easier, and more convenient, better meeting the user's needs. Attached Figure Description

In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified. "Several" means one or more, unless otherwise explicitly specified.

[0048] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0049] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0050] Example 1: See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6A quick-opening, non-plastic water-contact sealing cup lid includes an inner lid 1 and an outer lid 2 disposed on the inner lid 1. The outer lid 2 slides up and down relative to the inner lid 1. The inner lid 1 is provided with a locking mechanism 3 that can radially contract and expand. A self-priming water-sealing device 4 is provided at the middle position of the lower end face of the inner lid 1. The inner lid 1 is provided with a locking mechanism 5 for fixing the position of the outer lid 2 after it moves relative to the inner lid 1. The inner lid 1 is provided with a switch device 6 for unlocking the locking mechanism 5. The upper surface of the switch device 6 is on the outer lid 2. When the entire assembly (outer cover 2 in this embodiment) is pressed, after the outer cover 2 slides downward relative to the inner cover 1, the self-priming water sealing device 4 on the inner cover 1 will also move downward as a whole. The outer cover 2 causes the locking mechanism 3 to retract radially, and then the locking mechanism 5 will fix the position of the outer cover 2 at this time. In this way, the radial retraction position of the locking mechanism 3 is fixed. When the switch device 6 is activated, the switch device 6 will cause the locking mechanism 5 to release the fixation of the position of the outer cover 2 and restore it to its original state. At this time, the locking mechanism 3 on the inner cover 1 will expand radially, and the switch device 6 being pressed will cause the inner cover 1 to move slightly upward. Consequently, the self-priming water sealing device 4 on the inner cover 1 will also move slightly upward, which is conducive to the overall disassembly.

[0051] Example 2: This can be explained based on Example 1, such as... Figure 1 , Figure 3 , Figure 5 , Figure 8 , body 9 and Figure 10 As shown, a buffer elastic element 7 is provided on the lower end face of the inner cover 1. The buffer elastic element 7 is made of spring or silicone ring. This design helps to improve the overall buffering performance of the water-sealing cup lid, which is designed for quick opening without plastic contact with water. This also improves the buffering force of the self-priming water-sealing device 4 and extends its service life. In this embodiment, the buffer elastic element 7 is ring-shaped. The ring-shaped buffer elastic elements 7 are arranged concentrically with the center of the self-priming water-sealing device 4. This design is reasonable and easy to implement.

[0052] Example 3: This can be described based on Example 1 or Example 2, such as... Figure 1 , Figure 5 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 17 and Figure 18As shown, the self-priming water sealing device 4 includes a fixed base 41 integrally formed with the end face of the inner cover 1. A mounting base 42 is provided on the fixed base 41, and a return spring 43 is provided between the fixed base 41 and the mounting base 42. A self-priming water sealing component 44 is provided on the mounting base 42, which can achieve the function of sealing water and air. Further explanation: the self-priming water sealing component 44 adopts a U-shaped glass base (such as borosilicate glass, microcrystalline glass, or heat-resistant glass) or a U-shaped ceramic base, offering a variety of types and a wide range of choices. This facilitates the self-priming function and provides good water and air sealing.

[0053] like Figure 1 , Figure 5 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 17 and Figure 18 As shown, the mounting base 42 has several barbs 421 in the middle, which are integrally formed with the mounting base 42, greatly improving the structural strength. The fixing base 41 has anti-detachment holes 411 for installing the barbs 421. The barbs 421 are installed into the corresponding anti-detachment holes 411, which helps to prevent the mounting base 42 from detaching from the fixing base 41. In this embodiment, there are four barbs 421 and four anti-detachment holes 411, which is more conducive to the installation of the mounting base 42 and the fixing base 41. Further, the self-priming water sealing component 44 is fitted onto the mounting base 42, which is made of plastic material. This allows the self-priming water sealing component 44 to deform slightly with the plastic mounting base 42, thus preventing damage to the self-priming water sealing component 44 and ensuring better water sealing.

[0054] Example 4: Based on Example 1, Example 2, or Example 3, the locking mechanism 3 includes device grooves 31 evenly spaced on the upper surface of the inner cover 1, a ball 32 is provided on the device groove 31, a compression spring 33 is provided between the ball 32 and the inner side wall of the device groove 31, an inlet / outlet hole 34 is provided on the side wall of the inner cover 1 for the ball 32 to enter and exit, and a pushing foot 35 is provided on the lower surface of the outer cover 2 for the ball 32 to roll toward the inlet / outlet hole 34. In use, when the outer cover 2 moves downward relative to the inner cover 1, the push foot 35 also moves downward with the outer cover 2. The push foot 35 then contacts the push ball 32, which rolls towards the inlet / outlet hole 34. Simultaneously, the ball 32 compresses the compression spring 33, and the push foot 35 prevents the ball 32 from returning to its original position. The locking mechanism 5 then pushes the outer cover 2 back upward, thus allowing the ball 32 to protrude from the inlet / outlet hole 34 and be fixed in place. When the switch device 6 is pressed, the switch device 6 unlocks the locking mechanism 5, and the outer cover 2 returns upward relative to the inner cover 1. At this time, the push foot 35 releases its obstruction of the ball 32, and under the elastic force of the compression spring 33, the ball 32 returns to its original position in the device slot 31 (initial position), thus preventing the ball 32 from protruding from the inlet / outlet hole 34. Further explanation: the lower end face of the push foot 35 is set as a slope. The sloped push foot 35 pushes the ball 32 to roll towards the inlet / outlet hole 34 and protrude as the outer cover 2 moves downward. To further explain, the push foot 35 and the outer cover 2 are integrally molded, which greatly improves the structural sturdiness, and at the same time makes the up-and-down movement of the push foot 35 and the outer cover 2 more stable.

[0055] In this embodiment, there are six devices: slot 31, ball 32, compression spring 33, inlet / outlet hole 34, and push foot 35. One ball 32 and one compression spring 33 are installed in each slot 31. This arrangement is more conducive to the ball 32 being exposed and locked from the inlet / outlet hole 34.

[0056] Example 5: This can be described based on Example 1, Example 2, Example 3, or Example 4, such as... Figure 1 , Figure 5 , Figure 6 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 and Figure 16As shown, the locking mechanism 5 includes inner hooks 51 and abutments 52 spaced apart on the end face of the inner cover 1. The inner hooks 51 and abutments 52 are correspondingly distributed and connected by a return spring 53. Protrusions 54 are evenly distributed on the inner wall of the outer cover 2, each with a slot. The inner hooks 51 can be engaged in the slots of the protrusions 54 by the elastic force of the return spring 53. A switching device 6 is connected to the corresponding inner hook 51, which facilitates the simultaneous radial contraction of the inner hooks 51. At this time, the inner hooks 51 compress the return spring 53, allowing the return spring 53 to return the inner hooks 51 to their initial position and engage in the slots of the protrusions 54 under the elastic force. Furthermore, the abutments 52 and the inner cover 1 are integrally formed, greatly improving the structural rigidity. Even further, the protrusions 54 and the outer cover 2 are integrally formed, greatly improving the structural strength.

[0057] Among them, such as Figure 1 , Figure 5 , Figure 6 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 and Figure 16 As shown, there are four inner hooks 51, four abutments 52, four return springs 53, and four protrusions 54. This arrangement makes it easier for the inner hooks 51 to cooperate with the corresponding slots on the protrusions 54 to fix the outer cover 2 in its position after movement.

[0058] Example 6: This can be explained based on Example 5, such as... Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 11 , Figure 12 , Figure 13 and Figure 16As shown, the switch device 6 includes a switch rod 61 that can move up and down on the inner cover 1. A push button 62, integrally formed with the switch rod 61, is provided on the upper end face of the switch rod 61. A press hole for pressing the push button 62 is provided on the outer cover 2. Hook plates 63, which drive the inner hook 51 to move, are evenly spaced on the circumference of the push button 62. The hook plates 63 are integrally formed with the push button 62. A central cylinder 64, integrally formed with the inner cover 1, is provided at the center of the upper end face of the inner cover 1. The switch rod 61 slides up and down in the central cylinder 64. A return spring 65 is fitted onto the central cylinder 64 to automatically return the button 62 to its original position after it is pressed. When the button 62 is pressed down, it causes the switch lever 61 to move downward within the central cylinder 64. Simultaneously, the hook plate 63 on the button 62 causes the inner hook 51 to move towards the center of the inner cover 1. The inner hook 51 disengages from the slot of the protrusion 54, compressing the return spring 53. This causes the outer cover 2 on the inner cover 1 to move upward and return to its original position. In this embodiment, there are four hook plates 63, which facilitates the sliding of the inner hook 51 towards the center of the inner cover 1.

[0059] Further explanation as follows Figure 1 , Figure 6 , Figure 11 , Figure 12 , Figure 13 and Figure 16 As shown, the inner hook 51 is provided with a locking groove 51 for the hook plate 63 to engage. This engagement of the hook plate 63 into the locking groove 51 enables the inner hook 51 to move. The lower end surface of the locking groove 51 is inclined, which is a reasonable design and helps the hook plate 63 to better drive the inner hook 51 to move.

[0060] Example 7: This can be described based on Example 1, Example 2, Example 3, Example 4, Example 5, or Example 6, such as... Figure 19 , Figure 20 , Figure 21 and Figure 22As shown, this utility model also provides a water cup, including a cup body 10. The cup body 10 is made of a self-absorbing and sealing material, such as glass (e.g., borosilicate glass, microcrystalline glass, or heat-resistant glass, etc.) or ceramic, etc. The cup mouth of the cup body 10 is provided with a quick-opening, non-plastic-contact-water-sealing lid 20 as described above. This self-absorbing and sealing material cup body 10 and the self-absorbing and sealing device 4 can achieve a complete self-sealing effect. The seal between the self-absorbing and sealing material cup body 10 and the self-absorbing and sealing device 4 is achieved through the principle of self-sealing upon contact with water. The self-sealing material cup body 10 and the quick-opening, plastic-free water-sealing lid 20 are designed to prevent water and air leakage, thus avoiding the need for plastic contact in existing technologies. From adding water to drinking, there is no plastic contact, achieving zero pollution. Utilizing the properties of glass or ceramic, the self-sealing material cup body 10 and the self-sealing device 4 mutually attract each other to form a sealed air vent and water seal. This helps to more tightly seal the quick-opening, plastic-free water-sealing lid 20 onto the cup opening of the self-sealing material cup body 10. Furthermore, the outer wall of the cup opening of the cup body 10 is provided with a locking groove 101 for engaging with the locking mechanism 3 in the quick-opening, plastic-free water-sealing lid 20. In this embodiment, the locking groove 101 is annular along the outer wall of the cup opening of the cup body 10, which facilitates its cooperation with the locking mechanism 3. To further explain, a retaining ring 102 is provided on the inner side wall of the cup mouth of the cup body 10. The retaining ring 102 is integrally formed with the cup body 10. The retaining ring 102 and the self-priming water sealing device 4 in the quick-opening water-sealing cup lid 20 without plastic contact with water are tightly adsorbed together, which is conducive to achieving the effect of sealing water and air. In addition, the lower end face of the inner cover 1 of the quick-opening water-sealing cup lid 20 and the cup mouth on the retaining ring 102 form a cavity. At this time, the cavity is in a vacuum state, which is conducive to tightly closing the quick-opening water-sealing cup lid 20 on the cup mouth of the cup body 10, thereby achieving the effect of sealing water and air. The buffer elastic element 7 can play a buffering role. After the switch device 6 is activated, it is also conducive to loosening and venting the cavity formed by the lower end face of the inner cover 1 and the cup mouth on the retaining ring 102, which is conducive to removing the quick-opening water-sealing cup lid 20 without plastic contact with water. To further explain, there is also a cup shell 30 used to protect the cup body 10, which is beneficial for protecting the cup body 10 and also for heat preservation. The cup shell 30 is preferably made of stainless steel, which is easy to implement.

[0061] like Figure 19 , Figure 20 , Figure 21 and Figure 22As shown, when using this utility model, simply place the quick-opening, water-tight, plastic-free sealing cup lid 20 on the mouth of the cup body 10, and then press the quick-opening, water-tight sealing cup lid 20. The outer cover 2 of the quick-opening, water-tight sealing cup lid 20 slides downward relative to the inner cover 1. At the same time, the quick-opening, water-tight sealing cup lid 20 will also move downward slightly at the mouth of the cup body 10. The pushing foot 35 will also move downward with the outer cover 2, and the pushing foot 35 will contact the pushing ball 32 to roll towards the inlet / outlet hole 34. The ball 32 will compress the compression spring 33, and the pushing foot 35 will also... This will prevent the ball 32 from returning to its original position, causing it to protrude from the inlet / outlet hole 34 into the retaining groove 101 of the cup body 10. The hook 51, through the elastic force of the return spring 53, can then be engaged in the retaining groove of the protrusion 54 on the outer cover 2. This facilitates fixing the outer cover 2 after it slides downwards, and the inner cover 2 moves downwards, allowing the lower end face of the inner cover 1 to form a chamber with the cup opening on the retaining ring 102. At this time, the chamber is in a vacuum state, and the self-priming water-sealing component 44 on the middle of the lower end face of the inner cover 1 is self-adhesive to the retaining ring 102 of the cup body 10. This helps to achieve both water and air sealing, and further helps to prevent leakage. The absence of water and air leaks better meets user needs. Since both the cup body 10 and the self-sealing water component 44 are made of self-sealing water materials, especially glass or ceramic, there is no plastic contact throughout the process, which better meets users' safe drinking water requirements. When opening is needed, simply press the button 62 downwards. The button 62 will drive the switch rod 61 downwards in the central cylinder 64. Simultaneously, the hook plate 63 on the button 62 will drive the inner latch 51 to move towards the center of the inner cover 1. The inner latch 51 will disengage from the slot of the protrusion 54, thus allowing the inner latch 51 to disengage. The compression of the return spring 53 causes the outer cover 2 on the inner cover 1 to move upward and return to its original position (initial position). At this time, the push foot 35 will remove its obstruction to the ball 32. Simultaneously, under the elastic force of the compression spring 33, the ball 32 will return to the device groove 31 (initial position) and be released from the locking groove 101 of the cup body 10. At the same time, the inner cover 1 will move upward as a whole due to the buffer elastic element 7. Thus, the chamber formed between the lower end face of the inner cover 1 and the cup opening on the retaining ring 102 is not in a vacuum state, which is conducive to better removing the quick-opening, non-plastic water-contact sealing cup lid 20 from the cup opening of the cup body 10.
